It looks like the initrd is becoming obese. Adding "-m 168M" makes it
boot (qemu defaults to 128MiB). Not sure what to do about it.

OMG. I've ran the other system tests, but somehow missed "basic". Oops!

Anyway, the problem is that the parted script gets a negative size for
TESTS=basic:

creating partition table with 2 partitions...                                         
DEBUG: (mkpart primary ext2 1048576B -19922944B set 1 boot on mkpart primary ext2 -19922432B 22020608B set 2 esp on)

The attached commit fixes it; although there are other default sizes in
(gnu system vm) that may need adjustment after
ecf5d5376979fadd971559367bf553df89fcc62b.

Currently running *all* system tests, but it's going to take a while!
